答案:
$65 - 50 = 15$
$53 + 16 = 69$
$13 - 4 = 9$
$12 + 8 = 20$
$18 - 7 = 11$
$52 + 24 = 76$
$14 - 3 = 11$
$19 - 8 = 11$
$87 - 46 = 41$
$95 - 10 = 85$
$3 + 46 = 49$
$98 - 37 = 61$
$23 + 45 = 68$
$16 - 9 = 7$
$14 - 5 = 9$
$18 - 4 = 14$
$26 + 52 = 78$
$34 + 15 = 49$
$57 - 32 = 25$
$13 - 9 = 4$
$78 - (
46
) = 32$
$(
68
) - 50 = 18$
$7 + (
71
) = 78$
$13 + (
41
) = 54$
$56 - (
33
) = 23$
$(
19
) - 14 = 5$
$28 - (
16
) = 12$
$(
88
) - 25 = 63$
$2 + (
45
) = 47$
$(
43
) + 56 = 99$
$(
97
) - 23 = 74$
$67 - (
45
) = 22$
$(
69
) - 53 = 16$
$78 - (
65
) = 13$
$100 - (
20
) = 80$
$(
86
) - 16 = 70$
$17 - (
11
) = 6$
$(
86
) - 51 = 35$
$13 = (
7
) + 6$
$43 = (
64
) - 21$
答案: 解析:这些题目都是基础的加减法运算,考查对100以内数的加减掌握。通过移项可以轻松求解。
答案:
$78 - (46) = 32$
$(68) - 50 = 18$
$7 + (71) = 78$
$13 + (41) = 54$
$56 - (33) = 23$
$(19) - 14 = 5$
$28 - (16) = 12$
$(88) - 25 = 63$
$2 + (45) = 47$
$(43) + 56 = 99$
$(97) - 23 = 74$
$67 - (45) = 22$
$(69) - 53 = 16$
$78 - (65) = 13$
$100 - (20) = 80$
$(86) - 16 = 70$
$17 - (11) = 6$
$(86) - 51 = 35$
$13 = (7) + 6$
$43 = (64) - 21$
